We proposed the European Laboratory for Gravitation and Atom- interferometric Research (ELGAR), an array of atom gradiometers aimed at studying space-time and gravitation with the primary goal of observing gravitational waves (GWs) in the infrasound band with a peak strain sensitivity of 3:3 10−22=pHz at 1.7 × Hz. In this paper we detail the main technological bricks of this large scale detector and emphasis the research pathways to be conducted for its realization. We discuss the site options, atom optics, and source requirements needed to reach the target sensitivity. We then discuss required seismic isolation techniques, Gravity Gradient Noise reduction strategies, and the metrology of various noise couplings to the detector.

With projections based on the latest trends in atom interferometry and atom optics, ELGAR stands as a terrestrial candidate for detecting GW in the mid-frequency band, but could also enable new tests of fundamental physics and have applications in the geosciences. In this paper, we give details of the main technological bricks referenced in the ELGAR proposal [1]. In the laboratory environment, AIs are extremely sensitive inertial sensing experiments performing accurate and precise measurements of accelerations [2,3], rotations [4,5,6], and fundamental physics [7,8,9, 10, 11, 12, 13, 14, 15, 16, 17]. Such techniques have been refined and adapted to fulfill instrumentation roles in the applied sciences outside of the laboratory [18, 19, 20, 21, 22, 23, 24], moving this technology toward mobile, compact, and rugged experiments able to operate in varying and extreme environmental conditions. Based on such advances, large-scale AI experiments are already under development to pursue multiple scientific and technological developments; such as MIGA [25], VLBAI [26], ZAIGA [27], MAGIS [28, 29], AEDGE [30] or AION [31]. Motivated by the latest progress in sensitivity, reliability, and key advances in detection strategies with AI arrays [32], ELGAR envisions a transition from laboratory and field experiments to an decikilometric infrastructure to probe the mid-band (0.1 Hz to 10 Hz) GW spectrum. In this paper, we detail the technologies of the main systems of this instrument and identify the key developments needed. The realization a such large scale AI instrument ELGAR 5 will require new metrological studies: we also derive here the impact of various noise couplings to the detector. We organize the manuscript as follows: Sec.1 briefly summarizes the measurement concept of large-scale atom interferometry and the geometry of ELGAR. Sec.2 discusses three installation sites under consideration; these sites, located in Italy and France, are evaluated in terms of ambient noise. Sec.3 and Sec.4 details the atom interrogation process and the properties of the individual atom sources. Sec.5 gives insights to the suspension system required for the interrogation optics of the interferometer. Sec.6 presents the sensitivity of ELGAR to different sources of Newtonian Noise and presents a mitigation strategy. Sec.7 gives a complete view of the required metrology of the instrument, identifying and projecting the different noise sources in terms of equivalent strain. 1. The ELGAR detector Here we give a brief summary and schematic description of how the ELGAR detector is sensitive to gravitational waves. A more complete description of ELGAR geometry and signal extraction can be found in [1]. The basis of the detector is the atom gradiometer configuration shown in Fig.1: two free-falling atom interferometers placed at positions Xi;j along the x-axis are interrogated by a common laser beam which is retro-reflected by a mirror placed at position MX .

  • Minding Time in an Archetypal Cosmos
    Minding Time in an Archetypal Cosmos Matthew T. Segall What is time? Who can give a brief or easy answer? Who can even form a conception of it to be put in words? Yet what do we mention more often or familiarly in our conversation than time? We must therefore know what we are talking about when we refer to it, or when we hear someone else doing so. But what, exactly, is that? I know what it is if no one asks; but if anyone does, then I cannot explain it. -Saint Augustine, Confessions1 Time as a whole and in its parts bears to Space as a whole and its corresponding parts a relation analogous to the relation of mind to its equivalent bodily or nervous basis; or to put the matter shortly . Time is the Mind of Space and Space the body of Time. -Samuel Alexander, Space, Time, and Deity2 Sixteen-hundred years after Augustine’s death, despite humanity’s tremendous advances in scientific knowledge and technological power, time remains as mysterious as ever. On the one hand, the experiential passage of time is among the most mundane facts of our day-to-day lives. We say, “I am twenty-nine years old,” or “Let’s meet Wednesday for lunch,” and no one has the slightest problem understanding what we mean. On the other hand, as even Augustine, one of the most philosophically learned persons of his era, was forced to admit, when we stop to ask “What is time?,” our intellect is stunned into silence. Despite time’s mysteriousness, many thinkers have overcome this silence to venture an answer.

Located in the dining room (triclinium) of a wealthy Roman villa, the pavement, which contains five remarkably preserved panels depicting famous scenes from Greco-Roman mythology, is simply stunning in its artistic quality and scope. Constructed during the fourth century CE, the floor is a reflection of the considerable pros- perity of late Roman Cyprus and a window into the private world of a confident Mediterranean elite.2 Yet if the magnificence of the mosaic program has been conceded by all, its interpretation has proven more controversial. Although the scenes themselves are easily identifiable, being explicitly labeled by the artist, their meaning has been vigorously debated.3 Indeed, several prominent scholars, including the head exca- vator of the villa, W. A. Daszewski, have noticed an unsettling pattern in the layout of the panels.4 When read as part of a continuous sequence, the thematic content of these pagan scenes seems to mirror, in exact order, key scenes from the life of Jesus as depicted in the canonical Christian Gospels.

DOTTO/U TALKS ) f^op Lt=. 7 yt All rights reserved f PRINTED IN GREAT BRITAIN TO WALTER DE LA MARE INTRODUCTION The purpose of this book is to let the English reader see for himself what the Greeks, from Homer to Aristotle, thought about the world, the gods and their relations to man, the nature and destiny of the soul, and the significance of human life. The form of presentation is prescribed by the plan of the series. The book is to be a compilation of extracts from the Greek authors, selected, so far as possible, without prejudice and translated with such honesty as a translation may have. This plan has the merit of isolating the actual thought of the Greeks in this period from all the constructions put upon it by later ages, except in so far as the choice of extracts must be governed by some scheme in the compiler's mind, which is itself determined by the limits of his knowledge and by other personal factors. In the book itself it is clearly his business to reduce the influence of these factors to the lowest point; but in the introduction it is no less his business to forewarn the reader against some of the consequences.

  • Introduction. Dionysus in Rome: Accommodation and Resistance
    Fiachra Mac Góráin Introduction. Dionysus in Rome: accommodation and resistance Abstract: This introductory chapter provides a wide-angle history of the presence of Dionysus/Bacchus/Liber on Italian soil from the archaic to the early Christian periods, covering archaeological and literary sources. In parallel, it surveys the main scholarly trends on the Italian versions of Dionysus, and emplots the con- tributions to this volume in a history of scholarship. The main focus of the chap- ter, which is programmatic for the volume, is the interface of Greek and Roman cultures, and whether it is possible to identify and define (an) Italian version(s) of Dionysus. It posits two aspects to the Romans’ reception of Bacchus, which may be termed ‘accommodation’ and ‘resistance’. The interplay between these two levels of response will inform an analytic narrative that assesses the relation- ship between the Greek Dionysus and the Roman Liber, embracing interpretatio and religious polymorphism, and addressing some of the most important Diony- sian manifestations in Roman culture: the founding of the temple of Ceres, Liber and Libera; the Bacchanalia; the Liberalia; Roman leaders’ uses of Dionysus; the poets’ references to Bacchus; and a brief glance at the Bacchic-Christian inter- face. As ‘our oldest living symbol’,1 Dionysus/Bacchus has evolved over many different forms. Until relatively recently, scholars believed that he was an import from the East, and a late addition to the Greek pantheon. Rohde, Nilsson, Wilamowitz and Otto all subscribed to different versions of the Nietzschean myth that an ecstatic Dionysus cult was assimilated from Thrace and tamed by the influence of Apollo.2 This view was based on the god’s slight role in the Homeric poems, coupled with For discussion of Dionysus in Rome and bibliographical advice, I wish to thank Clifford Ando, Andreas Bendlin, Tom Carpenter, Michael Crawford, Elena Giusti, Dan Hogg, Duncan MacRae, John North, Donncha O’Rourke, Richard Seaford, and Peter Wiseman.

Box 1346 Ann Arbor, Ml 48106-1346 Abstract This thesis considers the development of the ideology of death articulated in myth and of theories concerning the possibility, in both mythical and 'secular' contexts, of attaining some form of immortality. It covers the archaic period, beginning after Homer and ending with Pindar, and examines an amalgam of (primarily) literary and iconographical evidence. However, this study will also take into account anthropological, archaeological, philosophical and other evidence, as well as related theories from other cultures, where such evidence sheds light on a particular problem. The Homeric epics admit almost no possibility of immortality for mortals, and the possibility of retaining any significant consciousness of 'self' or personal identity after death and integration into the underworld is tailored to the poems rather than representative of any unified theory or belief. The poems of the Epic Cycle, while lacking Homer's strict emphasis on human mortality, nonetheless show little evidence of the range and diversity of types of immortality which develops in the archaic period.

  • Jung and Aion: Time, Vision, and a Wayfaring Man
    Jung and Aion: Time, Vision, and a Wayfaring Man Lance S. Owens C. G. Jung stated in 1957 that the visionary experiences recorded in The Red Book: Liber Novus were the foundation of his life work: “My entire life consisted in elaborating what had burst forth from the unconscious and flooded me like an enigmatic stream . the numinous beginning, which contained everything, was then.” Liber Novus is now historically placed in a hermeneutic relationship with Jung’s subsequent writings. Jung composed the first page of Liber Novus in 1915. On this in- troductory folio leaf he graphically intertwined a prophecy of the future and the coming of a new aeon: an epochal turning-point in human con- sciousness. Though this revelation was foundational to his subsequent work, Jung did not initially feel free to publicly disclose its keynote. After several extraordinary near-death visions in 1944, Jung real- ized it was his duty to finally and openly communicate the central revela- tion recorded in Liber Novus.ThefirstmanuscriptpageofLiber Novus penned by Jung in 1915—deeply considered, dense with verbal and pictorial imagery formed in response to the Spirit of the Depths—and the complexly crafted commentary in Aion, composed three decades later, are fundamentally wed. They both declare the dawning of a new aeon. While each work might be studied as an independent text, one can only comprehend Jung and his struggle with Liber Novus in their conjunction. ho hath believed our report? and to whom is the arm of the Lord revealed? For he shall grow up before him as a tender plant, and as a root out of a dry ground.
